Didn't know posting another review would delete my previous so here's an edit: Not sure why my (last) review was found unhelpful by 3 people but I honestly recieved this product containing what I believe had to be RANCID vitamin D. Upon opening the bottle I noticed a somewhat "off" odor but having used this product in the past I figured it was still okay. WRONG! It gave me the s***s for a week! If that's what you're into then by all means, purchase this product and be ready to spend an hour playing 20 questions for a refund which you can apply toward another brand and have to pay shipping for... BTW I'm only logged back on so I can rate/review the Amino Focus which came in the same order. Found a mysterious chunk of something brown with what look like little hairs on it in the powder! I honestly looks like a dried up scab that fell off someones hand but hopefully it's a raw ingredient somehow. Regardless, due to these issues I will no longer be purchasing anything from RSP. They have lost me as a customer after 2 years of being satisfied with their stuff.

Nothing. Zero. Didnt improve my sleep AT ALL.

Just finished my first bottle, currently ordering more.. i love it. I have problems sleeping and i need vitamin D, so those are two main reasons i purchased it. i would totally, recommend it.

I got this product because I love RSP and their no B.S. products. I have a ton of problems sleeping and that causes alot of issues in general with ones body. I began taking these pills and after awhile my body began to absorb them and give me a more restful sleep. I still do not sleep well but, for some reason, I will wake up regardless of how much sleep I got in a more well-rested manner.

I didn't get much from this one.. Search Google for "testotrials" if you want something that works good.

I love this stuff! I have tried countless sleep help methods. This lets me sleep deeply but wake up feeling refreshed, not groggy!

I really like this product! Felt more rested in the morning! I will continue to use this product going forward.

Love this product ! Helps tremendously when it come to sleep and muscle recovery will continue to use

useless product. no changes and no results.

I’ve tried a few different supplements very similar to Z-Elite, but I definitely found the best results with this product (I’ve been using it for about 2 months). Also I loved how it was very light on my stomach and no crash or anything. Overall I say a very good supplement.

This is by far my favorite product from RSP. Z-elite gives me such a noticeable deper sleep. I️ wake up feeling well rested and ready to start the day. I️ definitely recommend this

I have been taking this produce every night for around two years now. Works great and would recommend it to anyone

probably everyone knows this product aleady ! amazing for digestive system (35 mg Zinc) and energy level during the day and at workout, due providing a very nice sleeping hours at night! no sugar great for cut and bulk season
